npplication filed August 22, 1525. Serial No. 51,795.

My invention pertains to ustable brack ets designed to pronde a wall support for various objects. I have elected todescribe and 1llustrate such a bracket for 5 iirthe plumbingtrade to support heaters,

boilers, and'the like, but it may be used for other purposes without departing from the utility and; general purposes of the invention.

Its objects are to 'ni'ovide'a'comparatively inexpensive adjustable bracket that may be quickly fixed to a wall, and manipulation of its several members constitute a firm support for articles of various base diameters.

I attain these objects by the provision, construction and assembling of the members and parts as shown in the accompanying drawings, in which Figure 1 is a plan view of the invention from above, showing the crescentic arms in a closed position.

Figure 2 is a similar view showing the crescentie arms spread to admit a tank or heater of larger base diameter.

Figure 3 is a side view of the invention fixed in position on a wall with a water tank thereon.

So far as known to the applicant the present custom in the plumbing trade is to provide solid brackets of varying sizes to fit various sized heaters and boilers. Not only is the diameter of these brackets fixed, but further variety must be provided to accord with lire ordinances in different localities in the matter of distance between wall and heater or boiler. It follows, then, that a stock of considerable size must be carried by a plumber to meet the varying conditions. Further, should a change of size of boiler, for instance, be required, the old bracket must be removed and complete new installation of the required size made.

Referring more particularly to the drawings:

1 1 indicate a rigid base bracket or support adapted to be fastened to a wall, 01, and on its horizontal surface provided with slots 1 1 adapted to receive bolts 22 22 indicate a pair of crescentic arms, one end thereof adapted to rest on bracket 1 and hinged thereto by means of bolts "22 through perforations and slots 11.

2 9fi indicate lugs cut in the periphery of said arms 2 2 and bent upwardly to pre vent side slipping of the object resting said arms 2 2" indicateconcentric slots in arms 2+2auapted to receive bolts 2 -4? for attachment to diagonal supporting reds 3--3.

2 indicates a bolt passing through corresponding perforations in downwardly projectinglugs 2, formed in' the distahends of arm's'il i 3-3 indicate di g rods adapted to attach to 2-= bymcan's of bolts t -2, the other end of the same being rigidly attached to the wall it will be readily apparent that movement outwardly of arms 22 in slots l l serves to separate said arms at theiri base while at the same time increasing the distance of the same from the wall 00. These two movements are compensated for at the points of support provided by rods 3-3 by movementof bolts 2 2 in slots 2"2".

By the movements above noted the lateral diameter of the bracket will be somewhat increased as shown in Figure 2 while the diameter of the curvature of arms 2-2 being unchanged the longitudinal diameter, that is front the wall outwardly, will remain as before. However, the fact that side contact with the tank Y is made only at four points, by lugs 2-2, and the arms having a substantial width, a larger tank will still rest fully on the upper surfaces of said arms.

T he distance between any one of lugs 2 and its diametrically opposed lug will be the approximate diameter required for a tank of any standard size.

To install: After positioning bracket 1 on the wall, and screwing or bolting the lower ends of rods 33 in place, a tank or heater is placed on the open bracket arms. Then said arms are closed about the tank until lugs ZE Z are in contact therewith, whereupon bolts 222 2 and 2 are permanently tightened and the installation complete.

Having thus disclosed my invention I claim as new and desire to obtain Letters Patent of the United States upon 1. An adjustable bracket of the character disclosed comprising a relatively small base bracket provided with multiple slots cut in the horizontal surface thereof; two semicircular arms adapted to rest on said bracket and removably hinged thereto, said arms being provided with multiple upwardly projecting peripheral lug"; and downwardly ex tending perforated. the distal thereof; means of fixing said distal ends in adjustable relative position; and means of supporting said arms in horizontal position.

2. An adjustable bracket ofthe character disclosed comprising a relatively small base bracket adapted to be rigidly positioned on a wall surface, and provided with two slots cut in the horizontal surface of the same, said slots being crescentically formed and directed outwardly from approximate the center of said bracket toward the outer corners thereof; two semi-circular arms supported on one end upon said base bracket and hinged in said slots by means of a perforation and bolt therethrough; said arms being provided with concentric slots approximately midway therein adapted to receive a bolt in slidable action; said arms being further provided with multiple upwardly projecting lugs at 20 the periphery thereof adapted to prevent side-slip of the supported article, and downwardly projecting perforated lugs at the distal ends thereof adapted to receive a bolt to maintain said distal ends in fixed relation; and two supporting rods adapted to be fixed to a wall surface at their lower ends and adjustably attached to said arms at their upper ends by means of bolts through perforations in apposition to said concentric slots.

In witness whereof I have signed this application and power of attorney this 12th day of August, 1925.

JAMES J. FITZGERALD.
